Manual Precision Surface Grinding Machine
JL-614(M), JL-618(MγSB), JL-818(M)
Joen Lih's precision manual surface grinder series features a machine structure made of advanced Meehanite cast iron, ensuring optimal machine rigidity and vibration resistance. The slideways are equipped with Turcite-B (wear-resistant material) and undergo precision scraping, ensuring smooth travel movements and maintaining high-precision machining.
In the SB series, the worktable employs steel ball rolling slideways, effectively reducing friction resistance on the sliding surface. This makes the lateral movement of the worktable smoother, particularly suitable for small-batch and diverse grinding operations.
Features
- Multiple Standard Worktable Sizes: Provide 6 inches x 14 inches, 6 inches x 18 inches, 8 inches x 18 inches. Multiple worktables are available to meet common machining needs in the market and the optional M series fine adjustment device allows for precise adjustments of up to 0.002mm.
- Spindle: Utilizing V-3 grade motor direct drive. With minimal transmission error and excellent lubrication, it can effectively extend the spindle's lifespan. The vertical feed adjustment of the grinding wheel head can reach 0.005mm.The optional M series fine adjustment device allows for precise adjustments of up to 0.001mm.
- Rigid Structure: The machine structure is made of advanced Meehanite cast iron, ensuring optimal machine rigidity and vibration resistance.
